SPECIFICATION forming part of Letters Patent No. 540,874, dated June 11, 1895.

Application filed May 31, 1894. Serial No. 512,969. (No model.)

To all whom it may concern.-

Be it known that I, WILsoN E. PORTER, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Stem -"Winding and Stem-Setting atches; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a View, partly in section and partly in elevation, of a watch constructed in accordance with my invention and looking toward its upper movement-plate and showing its winding-train; Fig. 2, a corresponding but; less comprehensive reverse view of the watch, looking toward its lower movement-plate and showing its setting-train; Fig. 3, a view of-the watch in vertical central section on the line a b of Fig.1, showing it adjusted for winding; Fig. 3 a similar view showing the watch adjusted for setting; Fig. 4, a detached broken plan view showing the bearing-plate and the manner of mounting it in the upper and lower movement-plates of the watch, together with the intermediate winding and setting wheels; Fig. 5, a detached view in side elevation showing the winding and setting arbor, the winding and setting wheels, and-the bearing-plate, Fig. 6, a detached plan view of the settingwheel; Fig. 7, a view corresponding to Fig. 5, but showing a modification of the means employed for coupling the winding and setting arbor with the winding-wheel; Fig. 8, a plan View of the winding-wheel shown by Fig. 7; Fig. 9, a view in side elevation showing a modified mode of coupling the winding and setting arbor with the setting-wheel.

My invention relates to an improvement in stem-winding and stemsetting watches, the object being to produce a simple, effective and reliable winding and setting mechanism, composed of few parts, durable in use, and not liable to derangement.

\Vith these ends in view, my invention consists in astem-winding and stem'setting mechanism having certain details of construction, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention, I employ a winding-wheel A, and a setting-wheel B, respectively located upon opposite sides of a bearing-plate O, which is mounted in the upper edges of the front and back movementplates D and D of the watch, in a plane at a right angle to the said plates, which are suitably notched to receive it. The said wheels A and B are constructed with central openings'to receive a longitudinally movable and rotatable winding and setting arbor E, which passes through them, and also through an opening 0, formed in the said bearing-plate. The outer end of the said arbor is screwed into a circular socketed head F, formed at the inner end of the stem F, the outer end of which is threaded, and screwed into the crown G, which is fitted over the outer end of the pendant H, the inner end of which is secured to the watch-case I, and the outer end of which carries the ring H. A spiral spring J, located in a chamber Hformed in the pendant, presses against the head F, and the opposite end of the chamber H, and exerts a constant effort to force the said arbor inward, and maintain it in its normal or winding position, from which it is moved into its setting position by pulling outward upon the crown against the force of the said spring. The said arbor E is alternately coupled with the winding-wh eel A, and

' the setting wheel 13, and its and their adaptation to that end is susceptible of wide variation. As shown in Figs. 1, 2, 3 and 5 of the drawings, the said arbor is constructed with a circular ratchet K, located about midway of its length, and having its teeth adapted to take into the teeth of a circular hub A, formed upon the upper face of the winding-wheel A. At its extreme inner end the arbor is furnished with a transverse coupling pin L, the projecting ends of which are received in slots 13, leading out of the central opening of the setting-wheel B, and a ranged in pairs opposite each other, the aligned slots of one pair standing at a right angle to those of the other pair as shown by Fig. 6. When the arbor is in its normal position in which it is held by the spiral spring J, the ratchet K is engaged with the toothed hub A, whereby the arbor is coupled with the winding wheel so as to rotate the same in case the crown is turned forward, while on the other hand, if thecrown is turned backward, ,the circular rack K will ratchet back as the term is, over the tooth ed hub A. The watch is normally therefore in readiness for winding. At this time the arbor being projected inward, the coupling pin L is maintained in a position beyond the plane of the inner face of the setting-wheel. Nhen it is desired, however, to set the watch, the crown is engaged by the fingers, and drawn outward, bringing the arbor with it, with the effect of disconnecting the circular ratchet K from the hub A, and drawing the pin L into one pair of notches in the setting-wheel B, which will. now be connected with the arbor, and be rotated in either direction thereby, while the winding wheel will be disconnected therefrom. It will thus be seen that the arbor is connected with either the winding or the set: ting wheel according to its position.

The winding-Wheel A is permanently in mesh with the intermediate winding-wheel M,.

which in turn is permanently meshed into the barrel wheel N, mounted on the barrel or spring arbor N. tingwheel B is permanently meshed, as clearly shown in Fig. 2, into the intermediate setting-wheel O, which meshes into the minute wheel 0'', which carries an hour pinion O meshed into by the hour-wheel 0 mounted on the center-arbor O, which also carries, the minute pinion 0 The particular construetion and arrangement of the winding and set? ting trains are, however, immaterial, and may be varied as desired, so long as each of themis in permanent connection with the winding opposite faces. of the bearing-plate O.

I may here remark that in prior construcwatches, the wheels employed to connect the stem winding and stem setting arbor with the winding and setting trains, have been thrown into and out of gear alternately, while in my construction, those wheels are permanently intermeshed with the trains, but not permanently connected with the winding arbor with which they are connected alternately It is apparent that in carrying out my in-. vention, changes from the construction herein described may be made. Thus, instead of employing the annular ratchet K, andthe hub. A for coupling the winding and setting arbor devices, which may or may not permit the reverse rotation of the winding arbor.

If desired, I mayadopt the construction shown by Figs. 7 and 8 of the drawings, in which the winding arbor P is provided with two coupling-pinspp', the projecting ends of which are arranged to take into slots formed in the winding-wheel P'and the setting-wheel P according to the position of the arbor which passes through both wheels, and through a bearing-plate P corresponding to the hearing plate 0 before described. The slotting of On the other hand the set i I invention.

the winding-wheel P is shown-in Fig. 8, while the slotting of the setting-wheel corresponds to the slotting of the setting-wheel shown by Fig. 6. In the construction shown by Fig. 9 of the drawings, the extreme inner end of the arbor Q is provided with a toothed head arran ed to en a e with atoothed hub Q b D b located upon the inner face of the setting wheel Q the said toothed head and hub takfact that in any embodiment of inyinvention the adaptation of the arbor to be coupled with the winding and setting wheels respectively is separate and independent, and located upon opposite sides of the bearing plate between the wheels.

Other variations than those described may obviously be made, and I would have it understood thatI do not limit myself to the constrnction illustrated and set forth, but hold 1 myself at liberty to make such changes as fairly fall within the spirit and scope of my I am aware, however, that it is old to alternately couple a rotatable and longitudinally movable arbor with wheels in connection with the winding and setting trains of a watch, and I do not, therefore, claim tha construction broadly. and setting-wheelsA and B, located; upon the Having fully described my invention, what I claim as new, and desire to secure by Letters 5 Patent, is tions of stem winding and stem setting 1,.
